What is "Upstream" and "Downstream" in ADRadioNet

Original Question: What is "Upstream" and "Downstream" in ADRadioNet by NagarjunaG

I am always confused about the terms - upstream and downstream in ADRadioNet. Can you clarify more on these streams?


Verified Answer: RE: What is "Upstream" and "Downstream" in ADRadioNet by NagarjunaG

Don't be bamboozled looking at that statement. Let me explain a bit more to clear your doubt.

 

The mote (E) is receiving data from the Router (R):  <=  on router's Downstream channel, which is nothing but the mote's Upstream channel.

 

The following is the flow...

  • The mote (E) is sending data to the Router (R):       => on mote's Upstream channel
  • The Router (R) is receiving data from the mote (E):  <=  on router's Downstream channel
  • The Router (R) is sending data to the Center (CP):  =>  on router's Upstream channel
  • The Center (CP) is receiving data from Router (R):   <=  on CP's Downstream channel


Question: RE: What is "Upstream" and "Downstream" in ADRadioNet by NagarjunaG

The ADRadioNet protocol defines 10 channels in each ISM band that is supported as part of the offering. On a given node, any channel or all channels can be chosen to send data, and one channel has to be chosen for receiving the data.

Consider the following scenario, where the sensor mote (E) is sending sensor data to the Center Point (CP) via the Router (R). One may choose the first channel (or any one of the available channels) as Downstream channel - to receive the data from upper orbits, and the remaining 9 channels can be used to transmit data to lower orbits. (a.k.a Upstream Channels).

The mote (E) is sending data to the Router (R):       => Upstream

The mote (E) is receiving data from the Router (R):  <=  Downstream

It shall be noted that there is no downstream channel for endpoints or no upstream channel for center point. This is because the end points will be positioned in the outermost orbit and obviously won’t be allowed to receive any data from the next higher orbits. Likewise as the center point does not have any other lower orbit, it does not need any upstream channel.

In-order to have successful communication of data, at least one of the up channel frequency of the nodes in upper orbits (EP/Routers) must be equal to the down channel frequency of the lower orbits (CP/Router).The acknowledgement is sent using the same channels as the upstream data, using the channel information that was added in the packet at each hop.


Question: RE: What is "Upstream" and "Downstream" in ADRadioNet by NagarjunaG

It is not very clear on what you meant by - "The mote (E) is receiving data from the Router (R):  <=  Downstream". Do you mean to say the mote has a downstream channel?
